SKATE CLAMP Filed Jan. 15, 1928 |H| I l I I Mi Ling Q- Patented May 27, 1930 UNITED STATES PATENT OFFICE ALFRED K. JOHNSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE ALFRED JOHNSON SKATE (10., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SKATE CLAMP Application filed January 13, 1928.

My invention relates to a skate holding device for sharpening skates.

One of the objects of my invention resides in providing a simple type of device for hold ing a pair of skates with their runners uppermost and in convenient position to be sharpened by the sharpening tool and wherein the skate runners are held by adjustable clamping jaws in such position.

Yet another object of my invention resides in the provision of the device of the character described composed of two spaced apart members adapted to be fastened to a board or support and a detachably interconnecting l5 rod, and wherein the upright jaw carrying members are arranged at an angle of inclination to the support board and are arranged to lie slightly inwardly so that the shoes to which the skates are fastened, may clear the uprights while the runners of the skates are held by the jaws of the uprights.

Another object of my invention resides in the provision of a skate runner rest or stop adjustably mounted on the jaw containing brackets so as to position the skate runners loosely between the jaws of the vise portion of the bracket before the jaws are clamped together and which stop also positions the predetermined amount of skate runner above the jaw surfaces for the sharpening operation.

Yet another object of my invention resides in the provision of this adjustable stop with double skate runner rests and the provision of means whereby it may be adjusted vertically on the jaw containing brackets.

These and other objects of my invention will be apparent from a perusal of the following speci cation when taken in connection with the accompanying drawings wherein Fig. 1 is a side view of my complete skate holding device with the skate shown in dotted lines in position;

Fig. 2 is an end view of the same Fig. 3 is a section on line 33 of Fig. 2;

Fig. 5 is a perspective view of the stop adjustably mounted on each one of the brackets.

a supporting base 6 which may be a table, a

board or what not. Each of the brackets con tain a main upright web 8 which has a foot 10 disposed at an acute angle withre spect to the plane of the web 8 so that the two brackets, when fastened to the support 6 as by means of the screws 12, will stand erect in inwardly inclined position as-shown in Fig. 1. In addition, each of the web portions 8 is provided with a hollow bored boss 14: through which detachably projects an interconnecting rod 16 so that the twoupstanding brackets carrying the jaws will be held in registered alignment and may be'moved toward or from each other as desired after the screws 12 have been loosened. The upper portion of the web 8 is provided with two outwardly flaring arms 18 and 20 symmetrically arranged on each side of a central upstanding flange 22. These arms 18 and 20 and the central-flange 22 are suitably reinforced angularly disposed ribs 24 for strengthening purposes.

The vertical and lateral portions 26 and'28 of the upwardly inclining arms 18 and 20 are provided with registering perforations to receive a round clamping rod 30 which is threadedon its outer end, as at 32, to receive the usual adjusting wing-nuts 84;. In addi tion, this rod 30passes through the central and upstanding web 22.

The top portion of the upstanding web 22 has integrally formed therewith two oppositely and outwardly extending clamping jaws 36 and 38 which register with co-operat ing clamping portions 40 and 42 of the arms 26 and 28 respectively. By reason of the fact that the web portions 8 and 22 and the arms 18 and 20 and 26 and 28 and 36 and 38 are all one integral metallic structure, there is a certain amount of resilience in the adjustment portions 36 and 4:0 and 38 and42 forming the jaws, which will permit these jaw portions to stand normally apart for theinsertion of the skate runners therebetween and which will permit these jaws to be clampingly engaged upon the skate runners when the wingnuts are tightened.

It will be further seen'that by reason of the ribs 24 extending along the outer faces of the webs and arms, I have provided a very rigid construction adapted to withstand the strains to which the holder is subjected during the sharpening operation.

A very important feature of my invention resides in the provision of a vertically adj ustable skate runner stop comprising, in the preferred instance, a horizontally disposed bracket 44 having spaced apart upstanding ends 46 and 48 having substantially V- shaped notches 50 and 52 adapted to receive the skate runners therein. This bracket is formed with a laterally extending arm 54 Fig. 3 of the drawing, passes and in addition, the outstanding arm 54 is provided with l a forward laterally extending tongue 60 perforated and threaded to receive an adjusting screw 62 having a wing-nut thereon so that when this screw is moved inwardly it will .clampingly engage the front face of the bracket whereby to hold the skate runner bracket or stop member in any vertically adj usted position. In addition, I provide this frontportion of the web 24 immediately beneath the vertical path of travel of the end of this fastening bolt 62, with my trademark or any suitable word formed of raised letters integrally made in the bracket so as'to give a rough, projecting surface for the end of this screw when tightened so as to hold it in vertically adjusted position.

It will thus be seen that when this bracket member 44 is adjusted to the correct height, the back portions of the skaterunners will I rest within the V-shapedgrooves-5O so that jaw carrying brackets.

":1 ters Patent is the skate runners may be held with the jaws 40 in open position at'a desiredheight above the top surfaces of these aws and thereafter the wing-nuts 34 may be operated to positive,- ly-clamp the jaws onto the opposite sides of the skate runners as thusheld.

In addition, it will be seen that by reason of the inward inclination of the two brackets, the skate runners are clamped at their front and back ends and in parallel relation and in a manner such that the shoes on the skates will not contact with the upstanding end This permits the skate runners to be held at a point inward from their ends by means of the brackets which brackets wholly clear the shoes.

- Having thus described my invention what I claim as new and desire to secure by Letoperating said jaws and means located below said jaws to receive and hold the skate runners with their edges to be sharpened disposed in a predetermined plane above the top level of the jaws.

2. In a device of the class described, the combination of two upstanding brackets provided with spaced apartjaws for receiving skate runners therebetween, means for oper ating said jaws and means located below said jaws to receive and'hold the skate runners with their edges to be sharpened disposed in a predetermined plane above the top level of the jaws and means for adjusting said means vertically on said brackets.

3. In a device of the class described, the combination of two end brackets, means for holding the same in upright position, said brackets having spaced apart jaws on their upper portions, a stop member having a horizontal portion and two spaced apart upstanding arms provided with: cradles for receiving the back edges of the skate runners for holding the sharp edges of the skate runners in predetermined position above the top edges of the clamping jaws and means for adjusting said stop members vertically and for .holding the same in vertically adjusted position.

4. In a device of the class described, the combination of a bracket comprising an upstanding web having a lateral flange at right angles thereto, a foot disposed at an angle with respect to said web and joining said lateral flange, a hollow boss formed in, said web and in said lateral flange, two arms outwardly projecting from said web substantially intermediate its length, each of said arms having an outstanding flange merging into the lower web portion and said arms and lateral flanges extending upwardly in substantially vertical formation and terminating in an inwardly and horizontall extendin ortion formin a i b C and in said lateral flange, two arms outwardly projecting from said web intermediate its length, said arms having an outstanding flange merging into the lower web portion and said arms and lateral flanges extendingupwardly in substantially vertical, formation and terminating in an inwardly and hori- -zontally extending portion forming a jawand said first mentionedweb extending upwardly and provided with opposed lateral extending branches providing co-operating jaws and a single bolt passing through said arms and central web and threaded on its opposed ends and wing-nuts engaging the threads of said bolt and an adjustable stop member comprising a horizontal portion having opposed upstanding ends formed with cradles and provided with an intermediate lateral extension slotted to receive the web flange therein, said lateral poredges of the skate runners in predetermined position adjacent the top edges of the clamping jaws, and means for adjusting said top members vertically and for holding the same in vertically adjusted position.

In witness whereof, I have hereunto subscribed my name.

ALFRED K. JOHNSON.
